Net.Data supplies several language environments to let you pass information to and from data sources, for example, the SQL language environment lets you pass native SQL queries to a database and the REXX language environment lets you invoke REXX programs.
Net.Data is designed to allow new language and database interfaces to be added in a pluggable fashion. These language environments are accessed as dynamic link libraries (DLLs) or shared libraries separate from the main Net.Data executable. The name of the DLLs are in the Net.Data initialization file and associated with a language environment name. Each language environment must support a standard set of interfaces defined by Net.Data. Net.Data loads the DLL specified in the initialization file the first time that a function call for a FUNCTION block specifying that language environment is encountered.
For complete details on language environments, see the Net.Data Language Environment Guide.
